Chronic Motor or Vocal Tic Disorder is a condition that involves involuntary and repetitive movements or sounds called tics. The phonetic transcription of this term is [krɑˈnɪk ˈmoʊ.tər ɔr ˈvoʊ.kəl tɪk dɪsˈɔrdər]. The 'ch' sound in "Chronic" is written as 'k' because it is actually pronounced as /k/. The 'a' in "Motor" is phonetically transcribed as /ɑ/ while the 'o' in "Vocal" is /oʊ/. Lastly, the 'c' in "Tic" is pronounced as /k/ instead of /s/.
Chronic Motor or Vocal Tic Disorder, also known as Tourette's syndrome, is a neurological disorder characterized by the presence of multiple motor tics and at least one vocal tic that persist for more than one year. Tics are sudden, repetitive, non-rhythmic movements or sounds that are involuntary, and individuals with this disorder experience them regularly. Motor tics involve involuntary contractions of certain muscle groups, such as eye blinking, facial twitching, head jerking, or shoulder shrugging, while vocal tics include sudden and involuntary production of sounds, words, phrases, or even obscene language.
The disorder typically emerges during childhood, usually around the age of 6 to 7 years, and its severity tends to peak during adolescence, before stabilizing or improving in adulthood. The exact cause of Chronic Motor or Vocal Tic Disorder is unknown, but it is believed to involve a combination of genetic and environmental factors. It is often associated with other conditions such as Attention-Deficit/Hyperactivity Disorder (ADHD) and Obsessive-Compulsive Disorder (OCD).
Diagnosis of the disorder requires the presence of multiple motor tics and at least one vocal tic. Although tics are involuntary, they may temporarily be suppressed, but doing so can lead to increased tension, which is relieved when the tic is eventually expressed. Treatment options for Chronic Motor or Vocal Tic Disorder include behavioral therapy, medication, and social support, aimed at managing symptoms and improving quality of life.
